Washington -- A water agency approved a $12.5 million irrigation project that will feed water from the Yakima River to the prominent Red Mountain AVA and wean local grapegrowers from the groundwater that currently irrigates area vineyards. Scott Revell, planning manager with the Kennewick Irrigation District, said the new system will pipe water to Red Mountain from a pumping station at Kiona, about 20 miles downstream from the current extraction point at Prosser.
